Well,
This is the second time in a row that I have had a fuel line leak on my stainless steel braided line. It is not the fittings that are leaking but rather small leaks in the hose. I was buying from a local dealer because it was a little cheaper, but now I want to buy the best as the piece I am replacing is ~15ft. long -10AN hose that runs from the fuel cell in the back to the regulator by the carburetor. I am leaving wednesday for the Div 7 NHEA Summit series finals, which doesn't give me much time, so:
What is the best brand of stainless steel braided hose?

I've used all those that you listed except for XRP .. Never had a problem with any of them with their hose or fittings.

Is it Bonaco lines you are using? I get my hose from G&J Aircraft on south Sultana in Ontario. I've not had any problems with it. I forget the brand they sell but it is something like Goodman.

Only stuff I have seen problems with is the "inexpensive" generic brands a few mail order places are selling.
I use XRP & AeroQuip & have had no problems.
You are very close to one of the biggest jobbers of XRP in CA.
Have you checked with them?

Pat,
Talked to them today. They use XRP hose, they mention that race fuel tends to deteriate the hose a lot faster than regular fuel (verified that with a co worker that was teamed up on a dragster crew back in the day). He mentioned that the combination of the race fuel, and heat that the life can be greatly reduced.
It is occuring in an area of the -10AN hose close to the regulator (which is higher than the fuel cell). So my thought is that after a race and before the next race (which is when these leaks seem to occur) the fuel in the line reaches a height equal to the level in the tank, thus allowing air into the higher portion of the line, allowing it to dry out with heat from the engine, allowing for premature failure." I seem to think that is whats happening.
